Survival and water-balance characteristics of unfed adult Amblyomma cajennense (Acari: Ixodidae)

The specific type of phospholipase A2 (PLA2) involved in formation of leukotriene B4 (LTB4) and platelet activating factor (PAF) in inflammatory cells has been controversial. In a recent report we characterized activation of the 'cytosolic' form of PLA2 (cPLA2) in human neutrophils (PMN) permeabilized with Staphylococcus aureus alpha-toxin under conditions where the secretory form of PLA2 (sPLA2) was inactive. In the current study, generation of both LTB4 and PAF in porated PMN are demonstrated. PMN, prelabeled with [3H]arachidonic acid (3H-AA, to assess AA release and LTB4 production) or with 1-O-[9',10'-3H]hexadecyl-2-lyso-glycero-3-phosphocholine (3H-lyso-PAF, for determination of lyso-PAF and PAF formation), were permeabilized with alpha-toxin in a 'cytoplasmic' buffer supplemented with acetyl CoA. Maximum production of both PAF and LTB4 required addition of 500 nM Ca2+, G-protein activation induced with 10 microM GTP gamma S, and stimulation with the chemotactic peptide, N-formyl-Met-Leu-Phe (FMLP, 1 microM); LTB4 production was confirmed by radioimmunoassay. Removal of acetyl CoA from the system had little effect on LTB4 generation but blocked PAF production with a concomitant increase in lyso-PAF formation LTB4 and PAF production occurred in parallel over time and at differing ATP and Ca2+ concentrations. Further work demonstrated that: (i) maximum production of both inflammatory mediators required a hydrolyzable form of ATP; (ii) blocking phosphorylation with staurosporin inhibited production of both; (iii) the reducing agent, dithiotreitol, had little affect on LTB4 formation but slightly enhanced PAF generation. This study clearly shows that cPLA2 activation can provide precursors for both LTB4 and PAF, that maximum PAF and LTB4 formation occur under conditions that induced optimal cPLA2 activation, that a close coupling between LTB4 and PAF formation exists, and that, after substrate generation, no additional requirements are necessary for LTB4 and PAF generation in the permeabilized PMN system.     

The characteristics of the effect of point and classical massage on the hemodynamics of patients with a history of transient ischemic attacks in the vertebrobasilar system

Clinical and instrumental studies have revealed differences in effects of nerve ending and classic massage on hemodynamics in 41 patients early after transitory ischemic attacks in the vertebrobasilar area. Point massage produced more potent vasotropic effect, contraindications to it are minimal. It can be considered as a pathogenetic therapy aimed at correction of cerebral circulation in patients with vertebrobasilar area applicable early after acute cerebrovascular episodes.
